My first Android phone, a year old, has developed many problems: slow, acknowledges taps without doing anything, distorting horribly with hands-free in my car (though that might be the car), draining the battery even with the screen and all apps off, launching apps I didn't ask for..........ad nauseam. The maker says I should back up everything (which I've now done), reformat, then reload the stuff I've backed up. But is the problem in the phone itself, or in the stu ff I've backed up--and if the latter, how can I tell what I can and can't safely restore? In the meantime, I've bought a better phone. If I just move the SIM card and Micro SD card to the new one, will it get screwed up, too?
